Hello Everyone: I'm trying to etup clustering with S3_ping. I'm getting the below error message when starting up Keycloak in standalone clustered mode. NOTE: I did a test as the user on my Linux node using awscli. The username on the Linux box is the same as the IAM user in AWS. I gave list,read and write permisison(Policy) for the user in IAM 20:37:04,480 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([ ("subsystem" => "jgroups"), ("channel" => "ee") ]) - failure description: {"WFLYCTL0080: Failed services" => {" org.wildfly.clustering.jgroups.channel.ee" => "java.io.IOException: bucket 's3-ping-keycloak-sothebys-dev' could not be accessed (rsp=403 (Forbidden).
